The observatory is located on the roof of the new science center on the Rockville campus of Montgomery College. (The street address is 51 Mannakee St. / Rockville, MD 20850.)

There is ample and free parking around the Science Center.

Use the main entrance and take the stairs or elevator to the 4th floor. You should be in Stairwell 1 or Elevator 1. The Observatory Guest Nights begin in room SC 400. If you are late and the group has already gone up to the roof, one of our students will assist you in getting upstairs.
